Abstract
Despite advances in therapy, advanced ovarian cancer maintains a dismal overall survival of 15-30%. Thus, the need for novel therapeutic modalities exists. Gene therapy represents one such approach and the purpose of this review is to present a logical rationale for the investigation of gene therapy for the treatment of ovarian cancer. The different strategies of gene therapy (molecular chemotherapy (prodrugs), mutation compensation, immunotherapy approaches, altered drug sensitivity, and virotherapy) for cancer treatment are discussed separately with attention to investigations with clinical applicability. Furthermore, the different viral vectors utilized for improvements in targeted therapy are presented. The advancements, discovery, and shortcomings are reviewed which lend itself to future directions. These future directions involve coxsackie-adenovirus receptor (CAR) independent pathways to improve infectivity and specificity to ovarian tumor cells, the potential of utilizing gene therapy as an imaging modality in detecting cancer, and incorporating the recently described technique of RNA interference. Due to the advancements in detection and targeting of ovarian cancer, coupled with the containment to the intraperitoneal cavity, gene therapy remains a promising treatment modality for ovarian cancer.

Advances in CAR-T Cell Therapy and CRISP combination
CAR-T cell therapy is a groundbreaking immunotherapy that has transformed cancer treatment, particularly in hematological malignancies like leukemia and lymphoma. It involves engineering a patient’s own T cells to express chimeric antigen receptors (CARs) that target and destroy cancer cells. The therapy has demonstrated remarkable success, achieving durable remissions in ...read more
Melatonin Signaling in Health and Disease
Melatonin regulates a multitude of physiological functions, including circadian rhythms, acting as a scavenger of free radicals, an anti-inflammatory agent, a modulator of mitochondrial homeostasis, an antioxidant, and an enhancer of nitric oxide bioavailability. AANAT is the rate-limiting enzyme responsible for converting serotonin to NAS, which is further converted to ...read more
